My GCSE's start on 14 May and I want to achieve 6s, 7s and 8s for majority of my exams. In terms of academic performance, I would call myself average because I do get decent grades. I do best in written subjects like English and History, than subjects like Maths. Last PPE's I got 5, 6 and 7s in English Lit, Lang and History, and in Maths I got a 4. Science I did average and got a 4. The problem with me is during my time in secondary school I have never constantly revised. I only revise 3-2 days before an exam and I've never stuck to a timetable. I applied to a prestige sixth form and got accepted, but they want me to get 6/7s and above. I've been trying to study hard, but due to not being used to revising consistently, I'm procrastinating a little. I want to improve Maths and Science the most but with only a months time, is it possible to get a least a 6 in maths or science, and is there any tips for me on how to revise/resources to revise with?
